摘　　要：合成了三种阳离子漂白活化剂,通过它们对棉织物的吸附来探讨阳离子漂白活化剂烷基链长短对于漂白的影响。结果表明,链段越长,棉织物对活化剂的吸附量就越多;当阳离子漂白活化剂的碳链长度过长时,会对溶液中的过氧乙酸产生空间位阻,从而阻止其对棉织物作用,使其白度不高。而碳链长度适中时,不仅对棉织物的亲和力大,又不会影响溶液中的过氧乙酸对棉织物的作用。因此,阳离子漂白活化剂的碳链长度并不是越长越好,过长反而会对漂白起反作用。Three kinds of cationic bleach activators were synthesized. Based on the adsorption of cotton fabrics, the effect of the alkyt chain length on performance of bleaching was studied. With the alkyl chain length was longer, the adsorption for cotton knit was much. Too longer chain length resulted in steric hindrance in solution, which prevented peroxy acids for cotton. The moderate length of alkyl chain length of cation bleach activators caused the large affinity and smaller action of steric hindrance. Therefore, too long alkyl chains length would cause back action.
